This PR contains two small, related updates to how Zarr chunks are handled.

  1. We now delete the encoding attribute at the Variable level whenever chunk is called. The persistence of chunk encoding has been the source of lots of confusion (see #2300, #4046, #4380, https://github.com/dcs4cop/xcube/issues/347)
  2. Added a new option called safe_chunks in to_zarr which allows for bypassing the requirement of the many-to-one relationship between Zarr chunks and Dask chunks (see #5056).

Both these touch the internal logic for how chunks are handled, so I thought it was easiest to tackle them with a single PR.
